Should I be wary of a roofer that starts talking "insurance claim" before he even looks at the job?

I called a local roofer and the first thing he asked if the roof damage was storm related. I responded that I couldn't be sure, nor could I prove it. Even though there were high winds over the weekend, the shingles may have just fallen off because of normal age deterioration, and the wind was just a catalyst. He asked for the name of my homeowner's insurance agent saying he'd look at the roof and maybe he and the agent could "work something out." Now if I get pinched submitting a fraudulent claim, it's my neck on the line, not his. What should I do?
